At a building site, two blue collar workers, Jack and Ray were chatting.
Jack: Ray, I've been attending night classes for five months now and I have an exam next week.
Ray: Oh…well, how's that going for you?
Jack: Great! I'm learning all this cool stuff! For example, do you know who Graham Bell is?
Ray: No.
Jack: He invented the telephone in 1876. If you took night classes you'd know that.
Ray: Oh…that's pretty cool I guess.
The next day, Jack hailed Ray at the site again.
Jack: Hey Ray, do you know who Alexander Dumas is?
Ray: No.
Jack: He's the author of 'The Three Musketeers'. You know, if you took night classes like me, you'd know that.
Ray frowned in annoyance but said nothing.
The next day, Jack came up to Ray again.
Jack: Hey Ray! Do you know who Jean Jacques Rousseau is?
Ray: No!
Jack: He's the author of 'Confessions'. If you took those night classes, you'd know that.
Ray had had enough. He straightened up and turned to Jack.
Ray: Hey Jack! Do you know who Danny Barton is?
Jack: No.
Ray: He's the guy screwing your wife. If you didn't take those night classes, you'd know that.
